Have you considered changing the voting thing to not allow for downvotes, only upvotes?
Downvotes are so rarely justified anyways, mostly they are given just because of personal preferences and upvotes are way more interesting both for the deck owner and the ones looking for a deck.
If you wanna go a bit further with it you could make it not just an upvote, but also make users select what they like about the deck (Fun, Strong, Cheap, Interesting etc.).
Then instead of just having an upvotes counter you could have like a chart similar to the mana cost overview showing what ppl actually think about the deck and why they felt like giving it an upvote.
